Anticorrosion battery terminal with short anchoring, without joint seams

Abstract

A seamless, short-anchor anticorrosion storage battery terminal is provided including an upper portion having a frustoconical hollow body with a cavity, the frustoconical hollow body adapted to emerge from the top of the battery, and wherein there is, at the end of the frustoconical hollow body with the greater cross section, a hollow lower portion whose internal cavity is coaxial with the cavity of the frustoconical body; the hollow lower portion having an uppersegment of cylindrical configuration and diameter greater than that of the end of greater cross section of the frustoconical hollow body, and a lower segment configured as a frustum of a cone, having at the end of greater cross section, means of anchoring and preventing rotation of the terminal including a circumferential projection whose wall defines a number of peripheral cavities opening alternately upward and downward. Alternatively, the means of anchoring and preventing rotation of the terminal may include a circumferential projection whose wall defines a plurality of circumferential mortises, or a circumferential projection which includes a plurality of orifices arranged circumferentially.

I claim: 
     
       1. A seamless, short-anchor, anticorrosion storage battery terminal, comprising an upper portion having a frustoconical hollow body with a cavity, the frustoconical hollow body adapted to emerge from the top of the battery, wherein there is, at the end of the frustoconical hollow body with the greater cross section, a hollow lower portion whose internal cavity is coaxial with the cavity of the frustoconical body; the hollow lower portion having an upper segment of cylindrical configuration and diameter greater than that of the end of greater cross section of the frustoconical hollow body, and a lower segment configured as a frustum of a cone, having at the end of greater cross section, means of anchoring and preventing rotation of the terminal including a circumferential projection whose wall defines a number of peripheral cavities opening alternately upward and downward. 
     
     
       2. A terminal as claimed in claim 1, wherein the internal cavity of said lower hollow portion is frustoconical. 
     
     
       3. A terminal as claimed in claims 1 or 2, wherein the hollow lower portion has at least one circumferential groove formed in its lower surface. 
     
     
       4. A terminal as claimed in claim 1, wherein said terminal is formed from an arsenic-free lead alloy. 
     
     
       5. A seamless, short-anchor, anticorrosion storage battery terminal, comprising an upper portion having a frustoconical hollow body with a cavity, the frustoconical hollow body adapted to emerge from the top of the battery, wherein there is, at the end of the frustoconical hollow body with the greater cross section, a hollow lower portion whose internal cavity is coaxial with the cavity of the frustoconical body; the hollow lower portion having an upper segment of cylindrical configuration and diameter greater than that of the end of greater cross section of the frustoconical hollow body, and a lower segment configured as a frustum of a cone, having at the end of greater cross section, means of anchoring and preventing rotation of the terminal including a circumferential projection whose wall defines a plurality of circumferential mortises. 
     
     
       6. A terminal as claimed in claim 5, wherein said terminal is formed from an arsenic-free lead alloy. 
     
     
       7. A seamless, short-anchor, anticorrosion storage battery termin comprising an upper portion having a frustoconical hollow body with a cavity, the frustoconical hollow body adapted to emerge from the top of the battery, wherein there is, at the end of the frustoconical hollow body with the greater cross section, a hollow lower portion whose internal cavity is coaxial with the cavity of the frustoconical body; the hollow lower portion having an upper segment of cylindrical configuration and diameter greater than that of the end of greater cross section of the frustoconical hollow body, and a lower segment configured as a frustum of a cone, having at the end of greater cross section, means of anchoring and preventing rotation of the terminal including a circumferential projection which includes a plurality of orifices arranged circumferentially. 
     
     
       8. A terminal as claimed in claim 7, wherein said terminal is formed from an arsenic-free lead alloy.
